FILLING ATTACHMENT FOR SIGHT-FEED OILERS.

Specification of Letters Patent.

Application filed November 2, 1901. Renewed June 28, 1905. Serial No. 26 1,449.

To all whom it may concern:

Be it known that I, FRANK B. GAERETsoN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Filling Attachment for Sight-- Feed Oilers, of which the following is a specification.

This invention relates especially to that class of oilers known as the sight feed oilers, in which one drop of oil at a time is fed up through a column of water and exposed to view, so that the action can be observed by sight and regulated to'feed various desired quantities of oil.

The especial object of this invention is to provide a filling device for sight-feed oilers which is combined with the body portion of an oiler of this class, so as to permit the pumping of oil into the upper part of the body ortion of the oiler by forcing water from t e lower part of the body portion back into the pressure-pipe.

A further object of this invention is to con-' nect an attachment of this construction to feed a supply of oil directly to the outlet of the oiler when desired without the necessity of having the same forced up through the sight-feed column.

To these ends this invention consists of the improved sight-feed oiler and of the combinations of parts therewith, as hereinafter 'described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying two sheets of drawings, Figure 1 is a plan view. of a sight-feed oiler provided with an attachment constructed according to my invention. Fig. 2 is a side view of the same, partially broken away; and Fig. 3 is a transverse sectional view thereof.

A sight-feed oiler of that class now exten sively employed for feeding oil to the main steam-pipes of engines, pumps, and other steam-supplied apparatus ordinarily comprises a body portion, which contains a volume of oil and which has a pressure-pipe for supplying water under pressure to the lower part of its body portion and a sight-feed column which is supplied with oil by a small pipe leading down from the upper part of the body ortion of the oiler to a nozzle controlled or regulated by a valve to vary the amount of oil passing up through the sightfeed column to the outlet, which maybe connected to a main steam-pi e. In the use of one of this class of oilers w en the supply of oil in its body portion becomes exhaustedor nearly exhausted it has heretofore been the practice to shut off the pressure from the oiler, drain out the water through a tap at the bottom of the body portion, and to pour in a fresh supply of oil through a cap at the top of the body portion of the oiler. The ordinary operation of filling a sight-feed oiler when practiced in this manner is necessarily a disagreeable and dirty operation, which takes considerable time and which is apt to be extremely wasteful, by reason ofthe fact that in drawing ofi the water from the body portion of the oiler a considerable percentage of oil is also frequently drawn off and wasted. The especial object of my present invention is to provide oil-supplying-connections for a sight-feed oiler which are arranged to pump a supply of oil into the upper part of the body portion, the lower part the pressure-pipe, thus providing for refilling a sight-feed oiler without the necessity of draining out any water therefrom and without the liability of waste due to drawing out more or 'less oil with the water which is wasted. To accomplish this object, in the s ecific construction which I have herein i ustrated I have combined a sight-feed oiler with an oil-supplying reservoir preferably having a glass body ortion and have-provided a convenientlyocated hand-pump for pumping oil from the reservoir into the body portion of the oiler, while in order to permit a su ply of oil to be furnished directly to the oi -outlet without requiring the same to pass up through the sight-feed column the pumpoutlet is controlled by two valves, one valve being opened when it is desired to force oil into the body portion of the oiler and the other valve being opened when a direct feed of oil is desired.

Referring to' the accompanying drawings and in detail, the oiler to which my invention is applied, as herein illustrated, comprises a body portion A. As illustrated in Fig. 3, water under pressure is supplied to the lower part of the body portion A through a pressure-passage B, controlled by a shut-off valve C. Extending up from the lower part of the body portion A is a glass sight-feed column D, having a nozzle supplied with oil from the upper part of the body'portion A by a pipe Patented Jan. 30, 1906.

so as to force the water from of the body portion back into E and controlled by a valve F to supply a graduated feed of oil to the outlet G. As illustrated in Figs. 1 and 2, the body portion of the oiler may also be provided with a gageglass H for showing the relative amount of water and oil in the body portion. The parts thus far referred to may be of the ordinary construction and need not be herein described at length. For refilling a sight-feed oiler of this construction an outlet from the bottom of the body portion A is controlled by a stop-cock J, and threaded into the top of the body portion A is a removable cap or cover I, so that in order to refill the oiler it has heretofore ordinarily been the practice to shut off the pressure by means of the valve C, remove the cap or cover I, drain out the water through the stop-cock J, and pour a fresh supply of oil into the top of the body portion. In refilling an oiler in this manner it frequently happens that oil is wasted, as it is extremely difficult to shut off the stop-cock J exactly at the instant when all the water has been drawn off from the body portion without permitting more or less of the oil to also run out with the waste water. My attachment for a sight-feed oiler of this class is especially designed to provide for more efficiently refilling the body portion of the oiler. As herein illustrated, a nipple 10 is secured to the body portion A of the oiler, and apassage extends from the nipple 10 to a T-fitting 11, having turn plugs or valves 12 and 13. The turn-plug 13 is connected, through elbows 14 and a-coupling 15, to the upper part of the body portion A, and the turn-plug 12 is connected, through the elbow 16 and coupling 17, to the oil-outlet G. Threaded into the nipple 10 is a supply-reservoir comprising a base-piece or fitting 18, carrying a glass body portion 19, which is held in place by a cover 20, threaded onto a central rod 21. Extending transversely across the fitting 18 is a passage 27, having a check-valve 22 near its outlet, and a small passage 23 for admitting oil thereto from the supply-reservoir. Movably mounted in the passage 27, which is chambered out to receive the same, is a pump piston having a rod 24 extending through a stuffing-box 25 and provided at its end with a handle 26.

By means of this construction by opening the turn-plug 13 and working the hand-pump just described a supply of oil'will be pumped into the upper part of the body portion of the oiler, forcing the water from the lower part thereof back into the pressure-pipe B, thus refilling or partially refilling the oiler as often as may be necessary, entirely dispensing with the drawing off of water from the oiler and the incidental Waste of oil therewith.

In practice my invention has been found especially valuable in situations where one engineer is expected to operate a number of separate pumps or engines by reason of the fact that the engineer can replenish the supply of oil in any one of the sight-feed oilers under his supervision by a few strokes of the hand-pump without wasting the time required for draining out the water, as has heretofore been the practice. In most situations I intend to provide a supply-reservoir and hand-pump for each sight-feed oiler. It is obvious, however, that a single supply-resefvoir and hand-pump may be used in connection with a number of oilers, being detachably secured to the oiler, so that it need be combined with the oiler only at the time when it is desired to replenish the supply of oil. Furthermore, by the use of my attachment I have provided a direct lubricating action from the hand-pump when desired, which may be secured by opening the turn-plug 12 and then operating the hand-pump, and I regard this as a feature of considerable importance, as a direct lubrication is desirable in starting up engines or pumps when the same have stood idle for considerable lengths of time or when the cylinders have become undesirably dry from any other cause. A

I am aware that numerous changes may be made by those who-are skilled in the art in practicing my invention, and Ido not wish, therefore, to be limited to the construction I have herein shown and described but What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a construction of the class described, the combination of a sight-feed oiler, an oilsupply pump, and connections from the oilsupply pump for refilling the sight-feed oiler or for furnishing a supply of oil directly to the outlet of the sight-feed oiler.

2. In a construction of the class described, the combination of a sight-feed oiler, a supply-pump, and valve-controlled passa es for connecting the oil-supply pump to re 11 the sight-feed oiler or to furnish a direct supply of 011a the part to be lubricated, as desired.

3. In a construction of the class described, the combination of a sight-feed oiler, a pressure-pipe therefor, an oil-supply pump, and valve-controlled passa es for connecting the oil-supply pump to re ll the sight-feed oiler or to furnish a direct supply of oil to the part to be lubricated, as desired, said parts being combined so that when the pump is operated to refill the sight-feed oiler, the water from the sight-feed oiler will be forced back into the pressure-pipe.

4. In a construction of the class described, the combination of an oiler comprising a body portion, a pressure-pipe leading thereto, a sight-feed passage leading therefrom, and an attachment comprising an oil-reservoir consisting of a base-piece with a pump-cylindervtherein, a glass body portion secured on the base-piece, a hand-operated pump-piston mounted in the pump-cylinder, and two valve-controlled passages leading from said pumps cylinder, one passage being connectmy hand in the presence of two subsc ed to refill the body portion of the oiler, and Witnesses.

the other passage being connected to furnish a direct supply of oil When it is not desired to 5 have the same pass through the sight-feed passage of the oiler.
